That is not only beautiful, but incredibly interesting as well! It is incredibly similar to the fx-991EX, but it has no solar panel and a couple of additional functions. The fx-991EX does not have the product function (ALPHA + x) in the upper right, simplify (ALPHA + (), MCD (ALPHA + *), MCM (ALPHA + /), int (ALPHA + +), intg (ALPHA + -), PreAns (ALPHA + Ans), and two functions that I don't recognize (ALPHA + FRAC) and (ALPHA + SQRT). There are also some localization changes to the trigonometric functions. What a wonderful find!
